We are looking for an experienced engineer with proven web3 builder experience to join a Web3 Startup.

You will design, develop, and implement applications that run on blockchains and decentralized infrastructure. As a fundamental part of a cross-functional team you'll deliver cutting-edge contracts and services that fuel and define the growing DeSci ecosystem.

• Minimum of 8 years as a Software Engineer. You’ve seen, broken, learned, and improved many things over the course of your career.
• At least 5 years of practical experience in web3, including hands-on work with applications that interact with assets on at least two blockchain layers.
• Ability to explain the inner workings of DeFi protocols such as Uniswap, Raydium, or Aerodrome.
• Familiarity with decentralised P2P networks like IPFS/libp2p, Radicle, or Ceramic is a plus.
• Mastery of Solidity/EVM code with deep knowledge of its tooling (e.g., Foundry), inner workings (e.g., ABIs, encoding, cryptography), and services (e.g., Tenderly, Alchemy, Etherscan).
• Proficiency with commonly used asset standards (ERC-20/721/1155) and hands-on experience with advanced standards (e.g., ERC-1167, 1967, 4361, 4844, 6551, 7683).
• A proven ability to analyze and optimize the performance of smart contracts and dApps, focusing on reducing gas costs and enhancing the user experience.
• Experience contributing to open-source blockchain projects or maintaining personal repositories.
• Hands-on experience writing, compiling, and deploying Solana programs is a plus.
• Robust frontend coding skills, particularly in React, Next.js, and TypeScript. You excel in debugging and working with React tooling (e.g., Tanstack, Zustand) and node.js-based applications.
• Knowledge of web3 user interface libraries in React (e.g., Privy, Alchemy, wagmi, viem).
• Outstanding ability to work with modern development tooling, including CLI scripting, Git, package management tools (e.g., npm), and your preferred IDE.

Soft Skills

• Strong collaboration skills and a passion for sharing knowledge, mentoring junior engineers, and fostering a culture of continuous learning.
• You’re constantly exploring new tools, methodologies, and ideas to improve workflows, enhance team efficiency, and address challenges creatively.
• You’re close to the cutting edge of blockchain and web3 technologies, keeping state-of-the-art developments in focus while balancing legacy considerations
